| Abstract | The purpose of the article is to determine the agrochemical properties of the soil and the productivity of field crop rotation under different fertilization and liming. Methods. Field, laboratory, measurement, calculation and comparison, analysis, statistical. The results. On average, in the three fields where liming was carried out under winter wheat, sugar beet and corn, in the first rotation, the increase in crop rotation productivity compared to the absolute control (without liming and fertilization) amounted to 0.37–0.63 t/ha kpo, in the second – 0.15–0.31 t/ha kpo depending on the dose of feces application. On average, for two rotations of crop rotation, this indicator for the application of 9.0 t/ha of feces was 0.42 t/ha kpo, and 13.5 t/ha – 0.47 t/ha kpo, that is, the increase was 12 %. Compared to the absolute control (without liming and fertilization), liming increased crop rotation productivity in the first by 0.37–0.63 t/ha kpo, in the second – by 0.15–0.31 t/ha kpo, depending on the dose of manure application . Soil liming helps to increase the profitability of mineral fertilizers. Thus, the introduction of 4.5 t/ha, 9.0 and 13.5 t/ha of feces increased the profitability of 1 kg of mineral fertilizers (N97P75K75) by 1.9 kg per hectare, 2.7 and 3.0 kg, respectively kpo The increase in the productivity of field crops for two rotations from potash fertilizers applied at a dose of 75 kg/ha per year on the background of N97P75 was 7 %, while on the background of the application of 4.5 t/ha, 9.0 and 13.5 t /ha of feces – 17–18 %. At the same time, the profitability of 1 kg of K2O mineral fertilizers increases from 2.9 kg kpo to 7.5–8.3 kg kpo. Conclusions. In the first rotation of the crop rotation under the influence of liming and fertilization, the productivity of 1 ha of the crop rotation area was from 4.75 to 10.07 t kpo depending on the place of introduction of feces under the culture in the crop rotation. It was more effective to apply manure under sugar beet than under winter wheat and corn. So, on average, for two rotations of crop rotation in the 1.0 CaСО3 + N97P75K75 experiment, the increase in crop rotation productivity was 9 and 6 %, respectively. | ||
